Crypto U.S. Senator Cynthia Lummis, a Republican from Wyoming, announced that she purchased $ 50,001 to $ 100,000 in Bitcoin (BTC) on Aug. 16, according to documents filed Thursday.

Lummis’ made the purchase less than two weeks after she and other senators tried to incorporate a pro-crypto change into President Biden’s infrastructure bill. The bipartisan effort, supported by Senators Mark Warner and Kyrsten Sinema, sought to ease the burden of crypto tax reporting on miners and wallet providers.

Controversial, Lummis’ amendment failed to make it into the Infrastructure Bill, which was passed by the Senate on Aug. 10. Senator Pat Toomey, a Republican from Pennsylvania, called the bill “seriously flawed” for imposing an “unenforceable” tax return on certain crypto companies.

The bill, called the Infrastructure Investment and Jobs Act, has yet to be voted on by the House of Representatives due to an adjourned process, according to the latest update dated October 1.

While it’s not entirely clear whether she owned Bitcoin at the time, the senator told Fox News in June, “I’m really excited because right after it kept falling.
